Tarragona Hydrogen Network

T-HYNET, the largest electrolyzer project in Spain

The initiative has been awarded with the European Commission Innovation Fund.

The formalization of the agreement with the European Commission to receive financing through its Innovation Fund, one of the main financing programs in the world for the development of innovative low-carbon technologies, took place last month. This financing marks a crucial milestone in the development of the largest electrolyzer project in Spain, with a capacity of 150 MW and strategically located in Tarragona.

Together with Enagás Renovable, Iqoxe, and Messer, Repsol will lead the T-HYNET consortium with the aim of deploying a large-capacity alkaline electrolyzer at European level, at the Repsol Petróleo Complex in the Tarragona industrial area. The facility will be designed to produce 2.7 tonnes of renewable H₂per hour, generating green hydrogen and oxygen for local consumers. As a result, the project stands to be a significant contributor to the widespread adoption of renewable hydrogen, with an important impact at an environmental, economic, and social level.

The project is part of the Hydrogen Valley of Catalonia and the Ebro Hydrogen Corridor. T-HYNET is also part of the European Hydrogen Backbone, which positions it as a key player in the hydrogen transmission facilitation among countries in the EU.

Electrolyzer uses and project stages

Using state-of-the-art technologies, the electrolyzer will be designed to minimize water consumption during the production of renewable hydrogen and oxygen. The renewable hydrogen will be used as a raw material in local industry, as an industrial fuel, in mobility, and by injection into the natural gas transportation network.

A second stage for expansion of the project is contemplated, reaching an impressive capacity of 1 GW. The construction of a hydrogen collector is also planned, to transport gas to consumers within the petrochemical center, as well as to Ecoplanta, the circular methanol plant close to Repsol. Ecoplanta Molecular Solutions, an innovative waste recovery facility located in El Morell, Tarragona, has also received recognition from the European Commission, securing financing in response to the Innovation Fund's call for proposals in 2021.
